Abstract: Provided is a defoaming agent showing an excellent defoaming property. Specifically, the defoaming agent includes a polymer containing as a polymerization component a polymerizable monomer (1) having a urethane bond and a fluorine-containing functional group and/or a silicone chain-containing functional group.

Abstract: The present invention provides a plasticizer for a vinyl chloride resin including an ester compound (A1) represented by General Formula (1): (in the formula, L's each represent an aliphatic oxycarboxylic acid residue having 3 to 18 carbon atoms or a cyclic ester residue having 3 to 18 carbon atoms, R1's each represent an alkyl group having 6 to 18 carbon atoms, R2's each represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, a represents a repeating number of the L, provided that the total of the plural a's is from 1 to 10, and x is an integer of 2 to 4), in order to provide a plasticizer for a vinyl chloride which has excellent compatibility with vinyl chloride resins and with which a vinyl chloride resin composition capable of providing a molded article having excellent freeze resistance and heat resistance can be obtained.

Abstract: In order to provide a polyester resin having excellent flexibility, transparency, solvent resistance, heat resistance, and water resistance and capable of being used for a protective layer of a fabric, and a resin-clad fabric obtained by forming a layer of the polyester resin on a fabric, the present invention provides a polyester resin including: a dicarboxylic acid residue; and a glycol residue, in which the dicarboxylic acid residue includes a terephthalic acid residue (a), an aliphatic dicarboxylic acid residue (b) having 6 to 12 carbon atoms, and a dimer acid residue or hydrogenated dimer acid residue (c), the glycol residue includes an ethylene glycol residue or diethylene glycol residue (d) and a branched aliphatic glycol residue (e) having 3 to 9 carbon atoms.
